Abstract

The purpose of this research is to get the precise formulation of the red ginger extract and carrageenan thus producing jellycandies with good quality and appropriate quality standard based on SNI 3574-2-2008 jelly candies. This study was conducted experimentally using a completely randomized design (CRD) with five treatments and three replications. The treatment in this study was JK1 = red ginger extract + carrageenan (41.50 + 7.50), JK2 = red ginger extract + carrageenan (40.50 + 8.50), JK3 = red ginger extract + carrageenan (39.50 + 9.50), JK4 = red ginger extract + carrageenan (38.50 + 10.50), and JK5 = red ginger extract + carrageenan (37.50 + 11.50). Data were analyzed using analysis of variance and in a further test using DNMRT at 5% level. The treatment provides significant effect on moisture content, ash content, acidity (pH), reducing sugar, antioxidant and colour, aroma, taste descriptively. The best treatment in this study was JK1 = red ginger extract + carrageenan (41.50 + 7.50), with a water content of 12.84%, ash content of 0.85%, the degree of acidity (pH) 6.47, reducing sugar 19.74% and antioxidant 2.77 µg/ml as well as having the characteristics of 3.13 (slightly yellow-brown colour), 2.10 (ginger-flavored red), 2.23 (spicy flavor) and 3.20 (slightly chewy texture) and an overall assessment of jelly candy ginger extract and preferably carrageenan by panelist’s. Keywords :Jelly, red ginger and carrageenan.

Abstract

One effort to improve the chemical properties of peat soils and the growth of rubber trees is by planting a legume cover crop Mucuna bracteata. The research aims to determine the chemical properties of the soil and the growth of rubber trees in peat soils without overgrown Mucuna bracteata with peat soils ex overgrown Mucuna bracteata and peat soil that overgrown Mucuna bracteata. The research was conducted in January – March 2016 in peat land at social plantation areal of PT. RAPP Teluk Meranti. The research was conducted by survey method where the determination of location specified by Stratified Random Sampling method and the determination of sample point specified by Simple Random Sampling method. The results showed that peat soil which is overground Mucuna bracteata has a pH value, C-organic, N-total, P-total, KTK, KB and the growth of rubber trees better than peat soils ex overgrown Mucuna bracteata and peat soils withouth overgrown Mucuna bracteata.Keywords : Peat soil, chemical properties, Mucuna bracteata, rubber.

This study aims to determine the effect of the interaction of sludge and phosphorus fertilizers and to obtain the best dose in increasing the growth and production of sweet corn (Zea mays saccharata Sturt) on inceptisol soil in experimental station of Faculty of Agriculture, University of Riau from January 2018 to March 2018 using Randomized Block Design (RAK) method consisting of two factors and three replications. The first factor was solid waste of palm oil (sludge) with 3 levels ie 0, 10 and 20 ton.ha-1, second factor of SP-36 fertilizer with 3 levels ie 75, 100 and 125 kg.ha-1. The data obtained were analyzed by using ANOVA and followed by HSD test at the 5 % level. The observed parameters were plant height, stem diameter, number of leaves, root canopy ratio, male flower appeared, female flower, cob diameter, ear length, cob weight per plot, weight of cob weighing and cob weight without weight. Sludge waste of 20 tons. ha-1 and fertilization of SP-36 doses 125 kg. ha-1 gave the best results for all observation parameters ie plant height, stem diameter, number of leaves, root shoot ratio, speed up male flowers appears and female flowers appear, the diameter of the ear, the length of the ear, the weight of the cob per plot, the weight of the cob weighs and the weight of the cob without the weights. Keywords: Sludge, SP-36 fertilizer, Inceptisol, sweet corn

In Indonesia oil palm has a significance for the national economy, in addition to being able to create jobs as well as a source of obtaining country (foreign country). This research aims to know the influence of biogas liquid waste against the growth of seedlings of Palm and get a dose of the best nursery Pre-Nursery. Research using randomized complete design (RAL) non factorial consists of 5 treatments and four replicates. As for the treatment of: P0: 0 ml liquid waste biogas/plant, P1: 20 ml liquid waste/biogas plants, P2: 40 ml liquid waste/biogas plants, P3: 60 ml liquid waste biogas/plant, P4: 80 ml liquid waste/biogas plants. Based on the results of the analysis of the variety that the average grant of liquid waste biogas influential real against the high seeds, number of seeds, leaves diameter of seedlings, seeds, and dry weight ratio of oil palm seedlings root header in Pre-Nursery age ≤ 3 months. The best doses against the growth of seedlings of Palm Pre Nursery-aged ≤ 3 months i.e. 80 ml/plant. Key words: oil palm, waste biogas
